Human travel beyond the Moon has been limited primarily due to the high costs, technological challenges, and the need for extensive life support systems for long-duration missions. Since the Apollo program, space agencies have focused on developing robotic missions and exploring Mars and other celestial bodies remotely. Additionally, the risk associated with deep-space travel and the need for advanced spacecraft capable of supporting human life over long periods have slowed progress. Future missions, such as NASA's Artemis program, aim to pave the way for potential crewed missions to Mars and beyond.
